OIL-CAN.

Specification of Letters Patent;

Patented June 2, 1908.

Application filed November 28, 1906. Serial No. 345,547.

To all whom it may concern:

Be it known that I, HENRY A. TELLERSON, citizen of United States,residing at Oakland, in the county of Alameda and State of California,have invented new and useful Improvements in Oil-Cans and Valves, ofwhich the following is a specification.

My invention relates to a device for normally closing the outlet spoutor passage of oil cans.

It consists in the combination of parts and in details of constructionwhich will be more fully explained by reference to the accom panyingdrawings, in which Figure 1 is a longitudinal section. Fig. 2 is aperspective view of the guide frame 11 It is the object of my inventionto provide a means for closing the discharge spouts of oil cans at alltimes when in use; said device being capable of operation by thecompression of the elastic bottom or sides of the can so that the valvemay be retracted and the passage opened for the discharge of oil afterthe can has been inverted or applied to the point to be lubricated.

A is an oil can of any suitable description and ithas an elastic orspring bottom 2, or the sides may be made elastic in case this form ofcan is to be used.

The operation being practically the same in either case, I will firstdescribe the can having the elastic bottom.

The nozzle 3 is made of considerable diameter up to the very tip, andthere it has formed in it a valve seat in which fits a valve 4, thisvalve being normally closed by the action of a spring 5, with ascrew-threaded base 3 which fits an opening in the can as shown. Thespace around the stem of the valve which extends downwardly through thespring, is sufficient to allow a free flow of oil up to the valve seat.Thus it is not necessary to withdraw the valve to a great eX- tent toallow the oil to flow around it and through the small discharge passageat the end of the nozzle.

The stem 6 of the valve has a loop or suitable attachment at the lowerend which connects it with the arm 7 of a bell-crank-lever, which isfulcrumed at 8. This arm of the lever extends transversely with relationto the nozzle, and the other arm 7* is connected by a link 9 with aplate 10. This plate 10 is slidable within a thin guiding frame 11, and

adapted to contact with the the plate has a slot 12, which is guided andslidable upon a pin 13 fixed in the guiding case. The plate is curved asshown, and its lower end extends across the casing and is guided againstthe opposite sides of the casing, as shown.

The plate has a small projection 15 extending through the bottom of itscasing, and a guided stem 16 has its lower end fastened to the elasticbottom 2 and its upper end 17 projection 15 whenever the bottom ispresse inwardly.

The operation will then be as follows: The

upward movement of the stem 16 communicated to the projection 15 andplate 10, causes the latter to slip upwardly within its guide andcasing. The diagonally disposed arm 9 is thus caused to press the arm 7a of the bell-crank-lever outwardly, and the lever turning upon itsfulcrum point 8, the arm 7 will be drawn downwardly thus compressing thespring 5 and retracting the valve 4 to allow an escape of liquid throughthe nozzle when the can is inverted. As soon as the pressure upon thebottom is released, the bottom returning to its normal position willrelieve the pressure upon the projection 15 and allow the parts toresume their normal position by the pressure upon the spring 5. Thenozzle or spout has a base of sufficient diameter to carry the valveactuating mechanism, and this base is screw-threaded to fit acorrespondingly threaded opening in the can. The nozzle and all theconnected mechanism may thus be introduced and removed together, noparts being secured to the interior of the can-body. The interior of thespout is of sufliciently larger diameterthan t e valve-stem, to allowthe contents to flow close to the valve-seat, and thus a small movementof the valve will be sufficient to admit the liquid instantly to thesmall discharge opening.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

The combination with a can having a screw-threaded opening and anelastic comressible side, of a discharge nozzle having a ollowscrew-threaded basefitting the can opening, a valve closable within thenozzle and having a stem extending into the can, arallel double wallsattached to the nozzle ase, between which the valve stem extends,
